State of pseudo-hashes, typed lexicals

Hi there, I am reading object oriented perl from Damian Conway (execellent book btw.) and he is using pseudo-hashes and typed lexicals. But he says that these features are experimental ... on the other hand, his book is some two years old, so I am wondering: Are pseudo-hashes and typed lexicals

Re: State of pseudo-hashes, typed lexicals

Hello Michael, They are experimental, and it's not a good idea to rely on them in production code. In fact, pseudo-hashes are on their way out. Typed Sorry to hear that. I liked the idea to have something more efficient than hashes ... on the other hand it is apparent that implementing

Michael Fowler wrote: Tearing out the pseudohash code gives an across the board 10-15% gain in speed in basic benchmarks. That means if we didn't have pseudohashes, normal hashes would be just as fast as fully declared pseudohashes! So don't mourn their passing. But

Using the B module?

someone can tell me where I can find some SIMPLY examples/tutorials of how to use the B package - for example it would be really nice to see code that reads a perl script and then walks over the corresponding AST and prints out all the nodes of the AST. thx, edwin günthner -- To unsubscribe, e

magic import of extensions?

Re: magic import of extensions?
